Four people, including a gunman, were killed Thursday morning in a shooting in downtown Cincinnati, Ohio, police said.

The Cincinnati Police Department tweeted that five other victims were injured, and three or four officers had responded to the scene and "engaged the shooter."

Earlier, police had announced they were investigating an active shooter situation and an "officer involved shooting incident" in the lobby and loading dock of a Fifth Third Bank building. It's unclear if the shooter died from police gunfire or a self-inflicted shot.

City officials were quick to condemn gun violence.

"There's something deeply sick at work here and we as a country need to work on it," Cincinnati Mayor John Cranley told media during a news conference.

"What a sick, tragic way for this day to begin. The scourge of gun violence leaves only loss," tweeted Councilman P.G. Sittenfeld.

Photos and videos from local reporters at the scene of the shooting showed a heavy police presence.
